Successful loan originators need to have a solid grasp of the concepts and calculations required in order to present clear solutions for their customers. While the use of a financial calculator or other software can be helpful in quickly completing difficult computations, it is crucial for mortgage professionals to understand the basic concepts behind common loan origination calculations; advanced number concepts allow the loan originator to look more deeply into the benefits of a transaction for the borrower. In this professional development online course, students will explore the fundamental financial calculations of loan origination. Concepts learned include principal and interest payments, income determinations, DTI and LTV ratios, periodic and per diem interest, and more. Students will learn formulas for these calculations and others, such as discount points and closing costs, and will apply their knowledge through several interactive scenarios to test their new skills.
